Project summary

The project aims at the development of glass-enamel coats for anticorrosive protection of metal to be used in corrosive media, in particular, coats to be used to protect details of deep-sea apparatus from marine and biological corrosion.

The effect of high-level anticorrosive protection ensuring by glass-enamel coats is caused by the fact that these coats have a unique combination of physical-chemical and technological properties that allows to reliably protect the surface of metal from chemical, biological and physical attack of corrosive media in a wide temperature interval.

It is intended to produce anticorrosive coats to cover the surface of metal (different kinds of steel) to be used in seawater. Seawater is a complicated finely balanced solution of numerous salts which also contains different kinds of living organisms, such as bacteria, suspended silt, dissolved gases and decomposing organisms. Therefore while developing protective glass-enamel coats resistant in seawater, it is necessary to take into account the influence of every one of the above-mentioned factors, as well as their complex.

As a result of the research it is expected to attain the following main parameters of coats: chemical stability in seawater: 0.01-0.1 mg/dm2, expansion temperature coefficient: 95-110*10-7 degrees –1, etc.

Specific character of the work will be the use of non-traditional, non-deficient raw materials, such as rocks, waste products of extractive, processing, chemical and metallurgical industries.

According to the information of the project authors, the use of such raw materials will reduce prime cost of final product by ~5-25% at the expense of reduction of material capacity and power-consuming of the process of production. At the same time, complex of physical-chemical and technological properties of produced composites remains, and in a number of cases improves.
